Abstract: Some embodiments provide a method for an agent executing on a Kubernetes node in a cluster. The method instructs a forwarding element that also executes on the node to process a flow tracing packet. From the forwarding element, the method receives a message indicating a set of flow entries matched by the flow tracing packet as the forwarding element processes the flow tracing packet. For each flow entry of at least a subset of the flow entries matched by the flow tracing packet, the method generates mapping data that maps elements of the flow entry to Kubernetes concepts implemented in the cluster. The method reports data regarding the set of flow entries along with the generated mapping data.

Abstract: Some embodiments provide a method for a module executing on a Kubernetes node in a cluster. The method retrieves data regarding ongoing connections processed by a forwarding element executing on the node. The method maps the retrieved data to Kubernetes concepts implemented in the cluster. The method exports the retrieved data along with the Kubernetes concepts to an aggregator that receives data regarding ongoing connections from a plurality of nodes in the cluster.

Abstract: Some embodiments provide a method that receives a request for flow entries associated with a particular Kubernetes concept. The method identifies flow entries that match the request. For each flow entry that matches the request, the method generates mapping data that maps elements of the flow entry to additional Kubernetes concepts. The method provides the flow entries with the mapping data in response to the request.
